Is an activated carbon filter the same as a water purifier?

No. An activated carbon filter removes chlorine, taste, odour, and organics — it does not remove dissolved salts, hardness, heavy metals, or microbial contamination. For drinking water safety, it is typically used as a pre-treatment or alongside a purifier.

Can it be used for borewell water?

Carbon filters can reduce odour from borewell water, but are not the primary treatment for iron or hardness. UNIWATER will recommend the correct sequence — typically sediment removal and iron filtration come before a carbon stage for borewell water.

How often does the carbon media need replacing?

Typically every 6–12 months for a GAC filter, depending on chlorine levels and flow volume. UNIWATER advises on your specific replacement interval and offers service plans.

Can I combine this with a water softener?

Yes — carbon filtration is often used before a softener to protect the resin from chlorine degradation, which can shorten softener life significantly. UNIWATER's survey determines the correct combination and sequence for your home.

Activated Carbon Filter

Eliminate chlorine, taste, odour, and organic compounds

UNIWATER's Activated Carbon Filter uses high-grade granular activated carbon (GAC) or carbon block media to adsorb chlorine, chloramines, disinfection byproducts, and organic compounds from municipal water supply. It is the essential treatment for homes on chlorinated municipal supply where the primary concern is taste, odour, and chemical residues rather than hardness or iron.

Signs you may need this system

Persistent chlorine smell from all taps

Water tastes chemical or flat

Slight yellowish tint from tank water

Musty or earthy smell from storage tank water

Dry mouth or irritation after drinking tap water

How it works

High-Grade GAC or Carbon Block

Coconut shell or coal-based activated carbon for effective chlorine and organics adsorption at high surface area

Taste and Odour Elimination

Measurably reduces chlorine levels and removes the chemical taste associated with treated municipal supply

THM and VOC Reduction

Reduces disinfection byproducts like trihalomethanes and volatile organic compounds formed during municipal treatment

Whole-Home or Under-Sink

Available as whole-house carbon filter for all-tap improvement, or compact under-sink unit for drinking water only

Multi-Stage Combination

Paired with sediment pre-filter and optional softener or RO for a complete multi-stage treatment solution

Problems it solves

Strong chlorine smell and taste from municipal tap water
Disinfection byproducts (THMs) from chlorinated supply
Musty or earthy odour from storage tanks
Colour and organic tint in water from ageing infrastructure
Chemical taste making drinking water unpleasant

Where it's used

Homes on municipal (corporation) water supply
Properties where chlorine is the primary concern
Pre-treatment before RO drinking water systems
Homes with overhead tanks susceptible to algae growth and odour
Commercial kitchens and food-service businesses needing odour-free water

The UNIWATER approach

UNIWATER evaluates your water supply type and chlorine level before selecting the right activated carbon configuration. GAC filters are suited for whole-home odour reduction; carbon block is used where finer particulate and organic removal is needed. We size the unit for your daily usage and install it at the correct point — typically after a sediment pre-filter and before any softener or RO system.
